Ponies and Pies.
I have watched some episodes, and all ponies, including Earth Ponies, have mage hand zero range, at the end of their hooves. That's the only way Pinky Pie could bake cupcakes. Like the Powerpuff Girls, they have no fingers. Do they have helper monkeys off screen cracking eggs and measuring flour?

The appeal is very simple. Friendship is Magic was invented by Lauren Faust, creator of two shows with similar fringe audiences (Powerpuff Girls and one other). The aim was to make a show parents could watch alongside their children.

The animation is pleasant, the comedy is hilarious, the characters aren't at all two-dimensional, plots are often interesting and even surprise us sometimes, the music is great (it's a musical show, ain't that awesome?), and on top of that it's all completely adorable.

Not everybody likes it. You have to be able to put up with a certain level of saccharine, and of course the names are kind of ridiculous. But try watching Lesson Zero, or Putting Your Hoof Down, or Party of One. You may be surprised.

Note how Derpy picks up eggs when she makes cupcakes only a goblin could love. Poor thing is cursed to fumble everything. I think they keep her around to make rain for the crops. Is Derpy a her?

I remade the races using the Advanced Race Guide's race creation rules.

Unicorns can load it, but only Earth Ponies can carry it into battle.
Applejack's big brother could bite down on the trigger bit, then the head of the hammer swings up from behind him and flattens whatever is 2 feet in front of him.

Pinkie Pie is holding a cupcacake with her forehoof and asks,"Yeah, how does this work?"
Twilight Sparkle gushes,"I think it's subatomic particles called glueons, but I'm still trying to prove they exist."
